Optimizing Math Libraries to Prepare for Exascale Computing This episode of Let’s Talk Exascale takes a brief look at the xSDK4ECP and hypre projects within the Software Technology research focus area of the US Department of Energy’s Exascale Computing Project (ECP). On the Spack Track At the annual supercomputing conference, SC19 in Denver, Colorado, there were Spack events each day of the conference. Join Our Team Looking for a challenge? Livermore Computing offers one of the most stable, stimulating work environments anywhere. Career opportunities in system administration, visualization, and data analysis emphasize creative technology, advanced research, and multidisciplinary collaboration. Top-Ranked Supercomputers at Livermore Computing Center Sierra Sequoia Lassen Sierra Our newest supercomputer, Sierra, is nearing completion and projected to provide four to six times the sustained performance and five to seven times the workload performance of Sequoia, with ~125 petaFLOP/s peak. The Collaboration of Oak Ridge, Argonne and Lawrence Livermore, also known as CORAL, represents an innovative procurement strategy to accelerate the development of high performance computing. Sierra is the Livermore system acquired as a result of the CORAL procurements, which will influence the modernization of future generations of computing throughout the NNSA complex. More about Sierra Sequoia Ranked among the world’s most powerful supercomputers, Sequoia supports two missions: quantify the uncertainties in numerical simulations of nuclear weapons performance and perform the advanced weapons science calculations needed to develop the accurate physics-based models for weapons codes. Sequoia is primarily water-cooled and significantly more energy efficient than comparable systems, which is essential to control operating costs. Sequoia has been ranked in the top ten on the Graph500 list since November 2012, indicating that it is one of the most efficient systems in the world for processing extremely vast (petabyte and exabyte-size) data sets. The Graph500 benchmark measures how quickly a system can search through a large data set—an important indicator of a system's usefulness as computer scientists increasingly use supercomputers to analyze massive data-intensive workloads in addition to executing traditional modeling and simulation tasks. More about Sequoia Lassen Lassen, an unclassified, heterogeneous IBM/NVIDIA system with the same architecture as Sierra but smaller, placed No. 10 on the June 2019 Top500 list with a High Performance Linpack (HPL) benchmark score of 18.2 petaFLOPS (18.2 quadrillion point operations per second) boosting its original 15.4 petaFLOP performance from the previous November.
